On April 22, the Dadu River Company of the National Energy Group completed the preparation of the flood relief plan and reservoir dispatching plan for the eight hydropower stations in operation on the main stream, and submitted them to the Yangtze River Water Conservancy Commission, Sichuan Provincial Department of Water Resources and other departments for approval and filing, marking the completion of the eight hydropower stations on the main stream. , tens of millions of kilowatt hydropower units have officially entered the flood preparation state, and are fully prepared to welcome the flood season.
The company's eight hydropower stations on the main stream of the Dadu River have a total regulated storage capacity of more than 4.5 billion cubic meters. They are important flood prevention barriers in the Sichuan-Chongqing region and the upper reaches of the Yangtze River. Due to the different regulation performance of each power station, the focus of flood control is different. The basin production command center takes the lead and based on the requirements of standardization, standardization and refined dispatch management, and combines the actual reservoir dispatch work and the requirements of various flood control weak points every year, from the refined dispatch principles, The plan will be comprehensively revised from multiple dimensions such as standardizing the operation and management of overflow facilities and clarifying dispatching rights and responsibilities.
In accordance with the practice of formulating flood control plans in previous years, the company mainly focused on the midstream control reservoir Pugou as the core, scientifically carried out joint dispatching and economic operation of cascade reservoirs in the basin in accordance with the flood season dispatching and application plan, and exerted the comprehensive water conservancy project on the Dadu River Basin as a whole and even Sichuan and Chongqing. Flood control function in river sections and the middle and lower reaches of the Yangtze River. This year, for the first time, the mainstream flood control plan was included in the research results of the "Joint Flood Control Dispatch Plan for Dadu River Monkey Rock and Below Cascade Hydropower Stations", which clarified the principle of floating control of the operating water levels of Monkey Rock and Dagangshan based on meteorological and water regime forecasts, providing a basis for joint flood control dispatch in the basin and The utilization of flood resources provides strong support, which is conducive to further leveraging the unified regulation advantages of the Dadu River Basin and improving the comprehensive benefits of water resources.
